Abstract

La présente concerne un procédé de gestion de tension d’une batterie (10) de véhicule équipé d’un réseau de bord avec au moins un consommateur électrique, comprenant une mesure de température (11) de la batterie (10), caractérisé en ce qu’on détermine (50) partir de la température (11) de la batterie (10) une tension minimale batterie (52) et une tension maximale de batterie (52) entre lesquelles la protection thermique de la batterie (10) est jugée assurée, on détermine (20) une consigne préalable (21) de tension de batterie, on détermine (70) une consigne finale (71) de tension de la batterie (10) en fonction de la consigne préalable (21) et des tensions minimale et maximale de batterie autorisées. Figure 1The present relates to a method for managing the voltage of a battery (10) of a vehicle equipped with an on-board network with at least one electrical consumer, comprising a temperature measurement (11) of the battery (10), characterized in that that determining (50) from the temperature (11) of the battery (10) a minimum battery voltage (52) and a maximum battery voltage (52) between which the thermal protection of the battery (10) is judged to be ensured , a preliminary setpoint (21) for the battery voltage is determined (20), a final setpoint (71) for the voltage of the battery (10) is determined (70) as a function of the preliminary setpoint (21) and the minimum voltages and maximum battery allowed.
